Model 400E Ozone Analyzer 
Instruction Manual 

THEORY  OF OPERATION 

 

P/N 04316 Rev: B 

 

231 

 

10.3.4.

 Pneumatic Sensor Board 

The pneumatic sensor board measures the absolute pressure of the sample gas up-

stream of the analyzer’s critical flow orifice. This measurement is used in calculating 

the O

3

 concentration of the sample gas (see Section 10.1.1).  

Also a Flow Meter, also located up-stream of the critical flow orifice measure the 

gas flow rate through the instrument. 

The following TEST functions are viewable from the instrument’s front panel: 

1.

 

Sample flow - reported in scc/min 

2.

 

Sample pressure - reported in in-Hg-Absolute 

The M400E displays all pressures in inches of mercury-absolute (in-Hg-A). Absolute 

pressure is the reading referenced to a vacuum or zero absolute pressure. This 

method was chosen so that ambiguities of pressure relative to ambient pressure 

can be avoided. 

For example, if the vacuum reading is 25" Hg relative to room pressure at sea level 

the absolute pressure would be 5" Hg. If the same absolute pressure was observed 

at 5000 ft altitude where the atmospheric pressure was 5" lower, the relative 

pressure would drop to 20" Hg, however the absolute pressure would remain the 

same 5" Hg-A.  

10.3.5.

 Relay Board 

By actuating various switches and relays located on this board, the CPU controls the 

status of other key components. The Relay Board receives instructions in the form 

of digital signals over the I

2

C bus, interprets these digital instructions and activates 

its various switches and relays appropriately.  

Heater Control 

A heater is attached to the Photometer UV Lamp housing and controlled by solid 

state relays located on the Relay Board.  

On instruments with IZS Options installed, an additional heater also controlled by 

the Relay board is attached to the IZS O

3

 Generator UV Lamp. 

Valve Options 

The solenoid valves of the Zero/Span/Cal Valve Option as well as the Sample/Cal 

valve included with the IZS option are controlled by a set of electronic switches 

located on the Relay Board. These switches, under CPU co ntrol, supply the +12VDC 

needed to activate each valve’s solenoid.
